﻿    <p>
      The <em>IfcMaterialProperties</em> assigns a set of material properties to associated material definitions. The set may be
      identified by a <em>Name</em> and a <em>Description</em>. The <em>IfcProperty</em> (instantiable subtypes) is used to express
      the individual material properties by name, description, value and unit.
    </p>

      NOTE&nbsp; The set of material properties can be assigned to an individual <em>IfcMaterial</em>, a set or composite of
      materials (<em>IfcMaterialConstituent</em>, <em>IfcMaterialConstituentSet</em>), or set or individual
      material layer (<em>IfcMaterialLayer</em>, <em>IfcMaterialLayerSet</em>), or a set or individual
      material profile (<em>IfcMaterialProfile</em>, <em>IfcMaterialProfileSet</em>)

      The following sets of material property definitions are part
      of this IFC release. They are direct instantiations of
      <em>IfcProperties</em> with the <em>Name</em> attribute
      holding the property set name.
